A decent programming editor should have builtin support for 
search/replace across multiple files. But if you need to do this
in a standalone form, try something like:

---- cut here, globalreplace.sh ----

#! /bin/sh

if [ $# -lt 2 ]; then
   echo "Usage: globalreplace oldstring newstring files" 1>&2
   exit 1
fi

oldstring=$1; shift
newstring=$1; shift

echo "Changing $oldstring to $newstring"

for file in $*; do
	if [ -f $file ]; then
		echo "Editing $file"
		mv $file tmpfile
		sed -e "s/$oldstring/$newstring/g" tmpfile > $file
		touch -r tmpfile $file
		rm tmpfile
	else
		echo "Error: $file not found"
	fi
done
